UNLABELLED
Hyperechogenicity is a sign classically reported to be in favour of a benign lesion and can be observed in many types of benign breast lesions such as hamartoma, lipoma, angiolipoma, haemangioma, haematoma, fat necrosis, fibrosis and galactocele, among others. However, some rare malignant breast lesions can also present a hyperechoic appearance. Most of these hyperechoic malignant lesions present other characteristics that are more typically suggestive of malignancy such as posterior shadowing, a more vertical axis or irregular margins that help to guide the diagnosis. Post magnetic resonance imaging, second-look ultrasound may visualise hyperechoic malignant lesions that would not have been identified at first sight and radiologists must know how to recognise these lesions.
TEACHING POINTS
• Some rare malignant breast lesions can present a hyperechoic appearance. • Malignant lesions present other characteristics that are suggestive of malignancy. • An echogenic mass with fat density on mammography does not require biopsy.

Angiolipomas are composed of mature adipose tissue and blood vessels. Spinal angiolipomas are rare benign tumors with a good prognosis, and most symptoms are due to progressive compression of the spinal cord and root. The treatment of choice is total resection without any additional therapy. We report a case of an epidural angiolipoma on the lumbar spine in a 69-year-old man with weakness of the lower extremities. Lumbar magnetic resonance images revealed a well-enhanced epidural mass. He underwent laminectomy, and the tumor was completely removed. Pathologic examination confirmed the tumor was an angiolipoma. The patient's symptoms gradually improved postoperatively.

Review
Fat-containing tumors of the salivary glands are uncommon. Their wide histological spectrum varies from pure lipomatous neoplasms similar to their cutaneous and soft tissue counterparts to mixed lipoepithelial lesions specific to the salivary glands. With few exceptions, these uncommon lesions affect mainly the elderly, with a mean age at presentation of ≥ 50 years and show a predilection for males. A few cases occur in childhood; some of them represent congenital lesions. In decreasing order of frequency, ordinary (soft-tissue type) lipoma, oncocytic lipoadenoma, non-oncocytic sialolipoma, and pleomorphic adenoma/myoepithelioma with extensive lipometaplasia are the main variants of fat containing tumors encountered in the salivary glands. While pleomorphic adenoma/myoepithelioma with lipometaplasia behave in the same way as their non-fat-containing counterparts, other lipomatous salivary gland tumors listed above are cured with simple excision and do not carry a risk of recurrence. Other lipoma variants (spindle cell lipoma, osteolipoma, fibrolipoma, angiolipoma, pleomorphic lipoma, lipoblastoma and hibernoma) are exceptionally rare in the salivary gland. Atypical lipomatous tumors/liposarcoma have been only rarely reported in the salivary gland and they behave in a similar fashion to their soft-tissue counterparts. Diffuse lipomatosis and lobular fatty atrophy are the two tumor-like lesions that might closely mimic sialolipoma, particularly in limited biopsy material without knowledge of the gross findings. This review summarizes the clinicopathological features of the main types of salivary fat-containing lesions and discusses their differential diagnoses.

Angiolipomas are rare primary benign tumors that can arise in the epidural canal and cause stenosis. Of the few cases of spinal angiolipomas described, most lesions have been located in the thoracic spine, and presentation of angiolipoma in the lumbar spine is very rare. The surgical management of a 39-year-old morbidly obese woman with angiolipoma that caused stenosis with neurogenic claudication and urinary changes is described. The lesion spanned L1-L2 and surgical management consisted of T12-L2 laminectomy and en-bloc resection of the lesion. During the latest follow-up, four years after the surgery, the patient's neurological symptoms showed improvement and there was no recurrence.

OBJECTIVE
Angiolipoma is a benign tumor that rarely occurs in the gastrointestinal (GI) tract. This case series was performed to increase clinicians' understanding of the diagnosis and management of GI angiolipoma.
METHODS
We evaluated the clinical presentations, diagnoses, and treatments of 3 patients with angiolipoma in the upper GI tract in our hospital and 27 cases reported in the literature.
RESULTS
Among all 30 cases of GI angiolipoma, 2 originated in the esophagus, 4 in the stomach, 2 in the duodenum, 1 in the jejunum, 7 in the ileum, 1 in the cecum, 9 in the colon, 2 in the rectum, and 2 in both the duodenum and colon.
CONCLUSION
Angiolipoma of the GI tract may be more likely to occur in middle-aged and elderly men and be located in the ileum and colon. The clinical manifestations generally involve upper GI hemorrhage and lower GI pain and obstruction. Computed tomography and endoscopy may be effective diagnostic techniques, but postoperative histopathologic examination is still the gold standard. The management of angiolipoma in the GI tract depends on the size and type of lesion. Most cases in the present series were managed by complete surgical resection, after which no recurrence was found.

Review
Spinal angiolipomas (SALs) are extremely rare benign tumors composed of both mature fatty tissue and anomalous vascular channels. We present two cases of SALs and review the clinical presentation, radiological appearance, pathological aspects, and treatment of this distinct clinicopathological mass. The patients' neurologic symptoms improved postoperatively and follow-up revealed no signs of tumor recurrence or neurological deficit. SAL should be considered as a differential diagnosis in patients with spinal cord compression. Magnetic resonance imaging is important for detecting and characterizing SALs. The gold standard treatment modality should be total resection.

Lipomas are relatively common benign neoplasms composed by mature fat cells. Apart from conventional lipomas, several other subtypes have been described in the oral cavity, including fibrolipoma, myxoid lipoma, angiolipoma, myolipoma, chondrolipoma, osteolipoma and spindle cell lipoma (SCL). Intraoral SCL is rare, representing from 1.4% to 9.8% of all intraoral lipomas. The aim of the present study is to report a case of a large intraoral SCL of the buccal mucosa affecting a 46-year-old male, calling attention to its clinical and histological features and to its successfull surgical conservative management. Lipoma, spindle cell, oral, buccal mucosa.

Angiolipoma is a rare subtype of lipoma that contains both mature adipocytes and a rich vascular component. Infiltrating spinal angiolipomas causes surgical challenges with potential on-table injuries to adjacent structures. We present a rare case of infiltrating spinal angiolipoma in a 76-year-old woman who presented with paraplegia and hydrocephalus. At the time of presentation, the patient was bedridden for 3 months due to a complete loss of motor power. Imaging examination revealed a lesion involving the T6 vertebra with compressive myelopathy. The patient underwent spinal decompression and resection of the lesion, which turned out to be an infiltrating angiolipoma by histological examination. This is a unique case because spinal angiolipoma is extremely uncommon and such lesions generally manifest without infiltration. This case report highlights the existence and importance of spinal angiolipoma as a differential diagnosis of chronic backache resulting in neurological deficits and hydrocephalus.

Lipomatous lesions are common musculoskeletal lesions that can arise within the soft tissues, bone, neurovascular structures, and synovium. The majority of these lesions are benign, and many of the benign lesions can be diagnosed by radiologic evaluation. However, radiologic differences between benign and malignant lipomatous lesions may be subtle and pathologic correlation is often needed. The use of sonography, computed tomography (CT), and magnetic resonance imaging (MRI) is useful not only in portraying fat within the lesion, but also for evaluating the presence and extent of soft tissue components. Lipomas make up most soft tissue lipomatous lesions, but careful evaluation must be performed to distinguish these lesions from a low-grade liposarcoma. In addition to the imaging appearance, the location of the lesion and the patient demographics can be utilized to help diagnose other soft tissue lipomatous lesions, such as elastofibroma dorsi, angiolipoma, lipoblastoma, and hibernoma. Osseous lipomatous lesions such as a parosteal lipoma and intraosseous lipoma occur less commonly as their soft tissue counterpart, but are also benign. Neurovascular and synovial lipomatous lesions are much rarer lesions but demonstrate more classic radiologic findings, particularly on MRI. A review of the clinical, radiologic, and pathologic characteristics of these lesions is presented.
